Electromagnetic coils - MM Inside Electronics [Explored]

Electromagnetic coils on an old graphics card.

 

From the basic electronic components I always found the coil the hardest to understand. In addition to the invisible current you suddenly also have this invisible magnetic force (flux). But it's a beautiful component making it a nice subject for this week's theme.

 

Thanks for all your comments and faves, they are really appreciated. Happy Macro Monday!
